To all whom mm; concern l'le it known and Ans-Use Lnn'nn'r, citizens oi.the United States, and residents, respectively, of

o the borough of Msnhattan and of the borough Queens, the city of NewYork,

" r State of New Yovln'pray that Letters l t i w and useful improvementsin sections "for Vehicle Construm whichthe following is a specification,relcrcnce being bad to the accompanying drawings, forming a part hereof.

This invention relates to non-metallic connections for use betweenmetallic units of a motor vehicle. The material employed is resilientand, in practice, is preferably rubher molded in suitable forms anddimensions for convenient assemblin" and securin to the units to beconnected. In its preferred application the invention will be found mostadvantageous when employed as a connection between the end of a vehiclespring and the frame of the vehicle. -More particularly, the inventionis concerned with a nonmetallic resilient connection of the characterdescribed in which the material is maintained under constant tension bytheload. it will be understood, as the description proceeds,

principles referred to above may be employcd by one skilled in the artwithout departing from the spirit of the invention. For the purposes ofthis application there have been illustrated, by way of example, threesuitable embodiments. Ql-Zcferring now to the drawings I I ifiigurc lisa view, partly in side elevation and partly in scction', of an imgrpveconnection applied between the end ofthe Tile spring: and a side framemember, l igurc 2 is a view in transverse section through the vehiclespring shown in Figure l, the elements of the connection properappeering in end elevation. Figure 3 is a sectional view of a connec-'tion oii somewhat dil'lcrent form in which the upper and lowerconnecting elements are normally in line with one another. of: Figure lis u view in longitudinal section rough supporting; bracket for still ant pe of connection in which an addi" lock of rubber or the L etween theend of 1st we, Amman F.

that various embodiments embodying the action is bracket to transmitstresses directly. there- 'Figure' 5 is a through the spring shown inFigure 4, the parts of the connection being shown in end elevation.

In the embodiment shown in Figure 1 the chassis of the vehicle, asexemplified by the side frame member a is supported from the ve'l i'nclespring 2) by means of the improved nonrmetallic connection which, asindicated hefeinbeforc, is of resilient material, such as rubber, and isnormally held under tension by the weight of the chassis. This type ofconnection is wholly of a non-metallic character and no metal of theelement to be connected to and supported by the other element comes incontact with the metal of said last-named element. member a is secured asuitable bracket as by bolts 0. This bracket has formed therein seats 00 which may be spaced apart and disposed substantially in the same vertical plane although the objects'of the invention might be realized in aconstruction in which the seats. while spaced, rested-in some otherplane. The problem is to connect the brachct 0 to the end of the spring6 so that the load will be carried and, at the same time, excessiverelative movement between the frame end the spring checked, that is,snubbed. The resilient connection shown in Figures 1 and 2 is formed ofmolded rubbel and includes a split body section (Z which embraces theend of the spring 7) and two angularly disposed link-like arms d, (1 theends of which are enlarged HSwll'ldlCfi-i'fid at (l The enlarged ends ofthe arm S d, d may be clamped within their respective seats 0 c, by capsof, 0 res actively, scoured removably' in place by bo 0. portion, (2'!of the resilient connection is clamped on to the end of the spring 6 bymeans of complementary clamping pieces 6 which embrace thespringand the:rubber and when boltcdtogethcr as by means of bolts e comprcssthe'rubbcr snugly on to the metalof the sm'ing. The ends (2* of the splitsections e body d of'the connection may be 5 ed as indicated so as tofalloutsid clamping pieces 6 and thereby iiaa u en 'agement between therubber meta. This clamping insisted-by enlarging the view in transversesection On the side frame.

The body end of the spring I) as indicated at b so that it will bepressed into the rubber when the clamping ieces e are bolted'together.practice, t e arms (1, d of the rubber will be of substantially equallength and form with the seats c, 0 in the bracket 0 an isoscelestriangle. The apex of the triangle will be found in the body d. The loadof the chassis will be carried through the downwardly extending arm (1which forms a resilient shackle connection between the end of the springand the frame a. This c0nnection 1s normally maintained under tension bythe load of the vehicle. Excessive upward movement of the frame a withrespect to the sprin d, as might occur in rebounding, is snub ed b meansof the other resilient arm (1', as wi 1 be apparent. The bracket andresilient arms may be so pro ortioned that the arms, when clamped at teir ends to the bracket and secured at their juncture to the end of thespring, are maintained under tension at all times, the tension of theone opposing the tension of the other. Movements in either direction areyieldingly resisted by means of-the non-metallic connectionbetween theframe and spring.

In the form shown in Figure 3 the frame A is supported from the spring Bby means of a vertical non-metallic resilient link I) while excessiverelative movements upward of the frame A is snubbed by the upwardlyextending link D of non-metallic resilient material. Two links D, D, maybe of similar construction and aredisposed in line with one another. Theframe A has secured thereto a bracket C which is formed with a seat C inwhich is clamped an enlar d portion ID of the link D A cap C is boltedover the seat C by means of bolts 0* and-clamps the link securely 'tothe bracket C. A similar seat C is formed in the upper part of thebracket C and the link D is similarly clamped in the seat C by means ofa cap C. The ends of the links D, D, in proximity tothe spring B may bemolded so as to embracethe contacting surfaces of the spring. These endsare clamped to the spring by means of complementary clamping f. pieces Ewhich are formed with suitable opposed seats E to secure the links D, D,in fixed relation to each other and to the spring B. r In Fi ure 4 aconstruction generally similar to t at-shown in Figure 3 is illustrated.Upper and lower non metallic resilient links. f, g, are clamped,respectively, to seats h, h, 1n a bracket i which is bolted to the sideframe member k of the vehicle. These links are secured in the samevertical line of clamping pieces are which em and clamped in fixedrelation to one another and to the vehicle thy means brace the springand retaining bolts m therefor. The ends of the links I, 9, within theclamp-- ing pieces m may be enlarged as indicated at f, g", tofacilitate the clamping. In this embodiment it is proposed to,inte'rpose a resilient block such as -n between the end of the spring Zand the bracket '5 so that stresses will be transmitted yieldinglytherebctwcen. This adaptation. may be important in the caseof the frontvehicle spring and where the spring is used to transmit the drivingforce, as in a Hotchkiss drive. The block 11 may be maintained in properreiation to the parts by engaging it with the end of the spring Z andseating it on its opposite face in a seat 2" provided therefor in thebracket L The embodiments shown herein will serve to indicate thepermissible variations in form and arrangement and emphasize thecharacteristic features of the improved connection.

What we claim is:

1. In combination with the spring and frame of a motor vehicle, a Whollynon metallic support interposed between an end of the spring and theframe and coinprisin a block of non-metallic yielding materia engaged atone end with the spring, a bracket carried with the frame and secured tothe lower end of said block, second block of non-metallic resilientmaterial connected at one end with the sprin and at the other end withthe bracket and disposed in. Fine with the first-named block, and athird block of non-metallic yielding material interposed between the endof the spring and the bracket to transmit longitu inai stresses there.

between.

2. In combination with the spring and frame of a motor vehicle, awholly-nonmetallic support interposed between an end' of the spring andthe frame and comprising a strip of non-metallic elastic materialengaged at one end with. the spring and so cured to the frame, a secondstrip of non metallic elastic material connected at one end with thespring and at the'other end with the frame upon the opposite sidethereof to oppose yieldingly the action of the first named strip, andmeans to maintain the strips under tension.
